Tractor coupling for agricultural attachment - has counter balanced yoke and flexible transmission to allow traverse sliding

摘要

The tractor coupling for agricultural attachments has a beam sliding within a fixed horizontal transverse beam under the action of a jack, and extending to either side of the fixed beam. The coupling to the attachment is fixed to one end of the sliding beam and is counterbalanced by a hydraulic reservoir fed by a hydraulic transmission and pump. The coupling to the attachment is articulated, the beams are coupled to three points on the tractor and the horizontal beam is braced by a vertical beam (2) making an inverted T shape chassis.
